How to Fix Disabled Task Manager, RegEdit, etc.?

New Folder.exe virus is one of the computer viruses that disables your task manager and reg edit. It also eats up  your computers speed that cause it to slow down. Portable storage devices like USB Flash Drives are prone to be infected by these kinds of viruses. Before opening your storage devices always perform a thorough scan with your anti-virus. In case you are infected, you can use trusted anti-viruses. But sometimes that doesn't work, if that happens to you, I recommend using Malware Bytes Anti-Malware.
It's ok if you can't buy the full version, the trial version is just ok. If you know how to use the windows command prompt, you can also use it to delete the virus but its harder using.
